welcome
lots of information and advice available here in the camera, lenses and accessory reviews and the articles
if you want to list your equipment, it might be easier to help your inquiry but remember
you will be able to succeed based on a combination of gear, skill, knowledge and even sometime luck
just enjoy photography and you will be a success
if interested in " experienced " equipment, I have had nothing but good luck dealing with other members in the Market Place ( which you can sort by country [ USA ] where the equipment is located )
